- Thanks to a comment on a previous video I've bought this small 5 volt uninteruptable power supply (UPS) module from ebay. It is designed to deliver 5 volts to your device even when the input has failed.
In this video I wire it up and put it through some basic tests.

I knocked something up with a TPS2113 but this looks soooo much cheaper thanks mate. I will pick one up. I don't think I have ever seen you make a magic smoke mistake :-)
+David Watts I buy at least half a dozen of everything I show then edit out all the mistakes ;-)
Ha ha, if that is trued I love you even more.
I could really see this being used as a flashlight (kinda like what you are doing in the video). While charging the battery(cell), you could still be using the flashlight and then disconnect and keep working. Especially useful for places where having a cord wouldn't be an issue, but just annoying at times (like working under a car doing mechanical work, or under a cabinet doing plumbing, etc, etc)
Really nice gadget! :)
Thank you. This is exactly what I want to make for my caravan. I will get the 12v one ,a few more cells and team it up with the solar panel you reviewed. It will the be used just to power the taps and led lights that don't get used much when I wild camp. This will be so much better than the leisure battery and a ton lighter. Thanks again for the great videos.
+play itcool You’re welcome. Just check the current limit on the 12v module in case it isn’t enough for your needs.
Adam Welch yeah it's only 0.5 amps at the 12v one. I'll have to check my pump. I might have to hunt out a 0.5amp one.
play itcool 500mA for a water pump seems quite low :(
I like the idea, but I think this one is actually bad. As far as I can tell this is a charger that charges the battery and a boost converter hooked to the same battery. If you have a load of (if charge current is set to 1A) 600mA - 100mA on the battery (whch means about the tp4056 will keep the battery at 4.2 volts indefinitely. It will be kept in the CV-state which (as far as I have heard) will cause the cell to break down.
A proper version of this would have an ideal diode with the input and battery as inputs and the boost converter as the output. And also the over discharge protection you mentioned.
I pulled a circuit from a cheap single cell power bank that had this capability, I had been using it with a solar panel to operate a wifi camera where I could not run any power cables, it worked for a while, then the board stopped working, I'm sure CUTS were overloading it, the camera drew less than 1 amp during the day, but probably went up to 1.25 amps at night with the infrareds on, it lasted several weeks, I'd love to find one of these with a 2 amp capability.
I am designing an "old school" nixie tube table clock at the moment. Old school meaning it uses only standart logic chips, transistors and a TCXO. Everything thru-hole of course. No microcontrollers, no RTC's... And I need some sort of a UPS for the 5V side of it for keeping the time when the power input is interrupted. I really hoped this board could be my solution but having no battery protection on the discharge side makes this thing pretty unusable... Maybe a battery with it's own protection may work though... Great video by the way, thanks.
Great vid, now the only thing I need is a signal that tells the battery voltage is getting too low to continue, with which I can let my Raspberry PI do a proper shutdown before it's simply been cut off...
Adam, as an FYI - how much did you spend in total on this unit (assuming you didn't have to make your blue box) Thanks
Very good little project you did there. Thanks for sharing the video!
+charles howard Cheers. It might help someone. :-)
Great little project that works, i do like you 3d printed box
My 3d printed box tends to warp :(
Check you out with your fancy gadgets. That microscope is great!
+Andrew Firth It’s excellent for the £32 I spent on it. Really handy.
name please
Enjoyed ur video.good soldering skills on those minute pins
Ya on all of those 18650 holders like that I have I have cut off those wing holder things
+James Holbrook A good tip. Cheers
Adam Welch that's just what I did because ya those things suck
And they work with button top cells only.
Using ABS plastic holders now.
CheapVlog Just add a Blob of Solder to the positive Battery Terminal and file it down a little so that it is somewhat flat.
these are quite good for experimenting with, they take AA,AAA and 18650. I know not suitable for this project but beats magnets for prototyping.

Just stumbled on your channel. Very concise and clear video. Thank you. I have a question, I'm trying to make a UPS for a raspberry pi in the car that will detect when the cigarette 5v adaptor loses power and runs off battery just long enough to initiate a proper shutdown. Do you think this module will work for me? I suppose I could add a relay to completely kill the pi to not discharge the battery?
... well, technically you can't charge and discharge at the same time.The current is only flowing in one direction. But that's the good about li-ion batteries. They don't have "memory" effect. You don't get penalty if you charge it before fully discharged.
Hi, the step up IC it's more likely to be an SD6271, the AL*** label correspond to it. BTW, it's not really any "smart" on the module, right?, or I missed out?, I mean the 5v output it's always connected to the boost converter, the ideal way it's something that only switches output voltage to the boost converter when the input voltage fails, I need something like this for a small 5v camera in case that the AC line fails. Still very interesting, thanks.
That looks great Adam, just the sort of thing I need. Is there a 5v 2.1a version of that board?
Hi great vid should get my modules in the mail soon :) .........can i ask/request a similar project or any info on a ups module like this that works with 12v car battery ? variable output voltage would be a bonus....thanks heaps :)
I cut off the plastic bits that curl in on the + side and it's a little easier to get the batt out.
+SidneyCritic ComedyHound A good suggestion. Thanks.
Devices with tight battery compartments often had a little ribbon, attached at one end, that would loop under one of the batteries. Pulling on the free end would pop the battery out. A bit of kapton tape stuck to the battery with a loose tab, or a strip cut from an old component bag running under the battery can be a good aid in getting it out.
Assuming this 5V UPS is plugged in, charging and has a USB LED attached, do you know if current is flowing from the battery to the LED or directly from the charging source? Did you have a chance to test this?
Most of these inexpensive board I've looked at don't have Dynamic Power Path / Load Sharing and prematurely wear out the battery since the load current comes from the battery and not the UPS input source.
Thanks for your videos. I learn something every time!
+Bunch Cheers. I think there’s a couple of extra tests I’d like to do with this. If it throws up some interesting results I’ll do a follow up video as soon as I can.
could be useful if it support 12v input and output as a ups for my router. power interruption in my country are quite annoying, just 1 or 2 second power cut my router reboots its self
Nice work!
There's a slightly easier way to do this, and it provides over-discharge protection too.
Combine one of these:
10Pcs 5V mini USB 1A 18650 TP4056 Lithium Battery Charging Board With Prote B5Q3
With one of these:
DC-DC Boost Converter 0.9-5V to 5V Step Up Module USB Charging Power Module B4
(Titles copied and pasted from eBay listings. You should be able to find them by doing an eBay search on each title)
The first item combines a TP4056 charging circuit with an over-discharge protection circuit, and at least on the version I received, it will allow charging while still supplying an output.
The second item is just a 5V voltage booster circuit, as you might expect.
I'd recommend putting a switch between the charging board's protected output and the voltage booster board, because the latter contains a LED which will be lit (and draining the battery) all the time while the battery is in circuit.
Yes, I think there are better ways to implement this - I would especially like the cell only to be called upon when the 5v drops off, but unless there is a way to bypass both the TP4056 board and the boost converter, there is going to be some issues with efficiencies.
The biggest problem I can see is the switch-over, presuming you're going to make a "real" UPS which supplies the output directly from the input while charging the battery and only supplies power from the battery when the input is not available. The switch-over needs to be fast enough that power-sensitive items such as a PIC or Atmel microcontroller won't notice any power outage, otherwise it's not really a UPS (the U is for Uninterruptable).
Super bro 👍
A Pass Through powerbank works too
I'm looking for a 5v out for a Bluetooth speaker, but I'm worried the ripple and noise. All surface mounted parts is optimal
What is the max output current from this UPS?
Thanks for this informative video, really interesting subject.
Good work , well demonstrated🙂
+anil sangani Thank you
Would be interesting to know how it operates its UPS function, from what I know 18650 don't like to be top-up charged, the 4056 will start charging from somewhere around 3.6v I think, I dont think it will be a safety issue more of a battery life issue.
+Alex Walpole The TP4056 datasheet says there is an automatic recharge function, but doesn’t show anymore info. I hope it allows the connected cell to drop a fair bi before the charge restarts. More testing required and a follow up video if it shows something interesting.
Im not sure who or where but I swear I remember BigClive, That Australian guy with the annoying voice or Julian doing a video on it
Interesting lil gizmo.
My powerbank as with many, does in fact have a pass though function. There is a 1 second delay in supply when power input is removed from power bank. The only benefit I can see is that your project doesn't have that changeover delay. Would that be correct? Neat project non the less. :)
+Matt Burrows Yrs that is right - no changeover delay at all. Explained a bit further why that is in my follow up video.
Thanks Adam. I guess the workaround for low voltage protection would be to use cells which have their own internal low voltage protection.
It would be much more useful if the data sheet, or some other source, could tell us _exactly_ how the over-voltage protection works. You answered other questions about it, but the details are too vague for comfort. For instance, is it fully-automatic, can it be adjusted or controlled manually? Does it charge to 4.2 Volts, or does it stop at a lower voltage, can it be adjusted manually? And so on.
Isn't it just a passthrough rather than a UPS?
Adam Welch The link for the 5v TP4056 UPS Module appears to be wrong
+MrBrymstond Cheers. An ‘&’ in the search text was breaking the link. Fixed now.
Adam Welch+ Thanks for the link...
good idea, thanks !!!
LOL what would happen if you put the USB input into the output. I gues it would just discharge it until it stopped.
It would proberly need an on/off switch in the battery lead to stop it discharging the battery when not in use, unless it was permantly plugged into a 5V source.
+FireballXL55 Another good reason for keeping that cable short! I didn’t think of that issue though. Thanks.
good video well done
You can just buy a TP4056 charger (with protection) and connect it to a boost converter.
+Asaf Shahar That is true. Worth looking at this though I thought.
Asaf Shahar that is exactly what I did. That way you have the over discharge protection. It does the same thing just with 2modules.
But in this setup the charger is powering the load which can cause all sorts of problems. You need some kind of high side switching circuit to charge the battery while power is on.
That's my approach to the problem. I've found that the charger board will keep on supplying power while charging the battery.
Hi. I have been looking at your videos alot since getting into solar and have took your advice on what products are good or bad from your reviews. I would like to contact you over email if possible. Is there any chance we could arrange that. My current setup is 2 250w solar panels with the epever 40amp solar charge controller. Kind regards. Kyle.
+kyle bell Hi Kyle. If you take a look at the ‘about’ page on my channel there is an email address available under ‘business enquiries’. You can email me on that and I will help if I can, but you might have to be patient with me - I get a lot of requests and messages these days.
Adam Welch. Thank you.
Adam Welch may be keep a option quick reply for 1$ or something 😝
Just add a 1S BMS board to your unprotected li-ion battery
I received two of these today and I can verify ~800mA output, not the 1A you're showing. Also, it won't change my iPhone - I've tried with a genuine Apple USB cable and it pulls 2-3mA and won't engage the cable/chip for some reason. Charges other devices ok but not my iPhone. Any ideas?
i want to bye it allready build !
I NEED A 3D PRINTER :(
hardly impressed, is it really just a TP4056 charging the cell and the 3426 is boosting from the 18650? yikes. just imagine if you had this thing setup for a long period of time, how much wear on the battery from being charged and discharged right up to 4.2v every 5 minutes!!!
+SuperBrainAK it shouldn’t get charged up too frequently. If you take a look at the tp4056 datasheet you will see that it mentions an automatic recharge setting. Now there isn’t much more detail but I think it will allow the cell voltage to drop quite a bit before it initiates a charge again. Someone else mentioned it will charge again at 3.6 volts.
The question is if the current draw from the connected device is high the tp4056 might not ever reach the completion threshold current. I’m going to try and investigate this and might do a follow up video.
